UNI-PEX / AU-300

This 300MHz band wireless tuner unit is designed to be installed in the BX series of desktop amplifiers. By selecting the microphone order function, you can prioritize reception of multiple wireless microphones on different channels in the 300MHz band. Also, once a wireless microphone is no longer in use, a new wireless microphone on a new channel can be received. One additional SU-3000A wireless tuner unit can be added.
